Maki Kaji, the Japanese publisher credited with popularising the numbers game Sudoku, died of bile duct cancer in his Tokyo home on August 10. He was 69.
His death was made public on Tuesday by Nikoli, the puzzle publishing company Kaji co-founded in 1980.
“Known as the Godfather of Sudoku, he was adored by puzzle lovers around the world and we would like to express our gratitude to all of you,” Nikoli said.
Kaji was a university dropout who worked in a publishing company before starting Nikoli, Japan’s first puzzle magazine.
Sudoku's origins are open to debate. Some say the game can be traced back to the 8th century and arrived in the Arab world from China through India. Others credit Leonhard Euler, an 18th century Swiss mathematician, as the game's creator. Earlier versions of the puzzle were published in French newspapers in the 19th century. However, US architect Howard Garns is generally considered to be the creator of the game's modern version, establishing it in the 1970s under the name Number Place.
Kaji took inspiration from Number Place to create the beloved gridded numbers puzzle as we know it today. It was first introduced in Japan by Nikoli in 1984 as “Suji wa dokushin ni kagiru”, loosely translated as “the digits must be single”. The name was later abbreviated to Sudoku by Kaji.
"It was a very interesting puzzle, fun to solve," Kaji said in a speech during the 2008 US Sudoku Championship. "But the name, Number Place, did not hit me. I wanted to create a Japanese name."
Sudoku gained prevalence outside of Japan in the early 2000s when puzzle magazines in the UK began publishing the game, which made its popularity skyrocket. The World Sudoku Championships have been held annually since 2006.
Commended as a way of sharpening mental faculties, millions of people around the world have made a habit of playing Sudoku on a near-daily basis.
Kaji remained an active part of the company he co-founded, creating and improving puzzles until he stepped down in July owing to ill health. He was credited with inventing other puzzle games such as Masyu, a logic puzzle consisting of black and white circles in a grid.
“I get really moved when I see a new idea for a puzzle which has lots of potential,” Kaji told the BBC in 2007.
“It is like finding treasure. It’s not about whether it will make money, it is purely the excitement of trying to solve it.”

Find the right policy for you
Don’t wait until the week you fly to sign up for insurance – get it when you book your trip. Insurance covers you for cancellation and anything else that can go wrong before you leave.
Some insurers, such as World Nomads, allow you to book once you are travelling – but, as Mr Mohammed found out, pre-existing medical conditions are not covered.
Check your credit card before booking insurance to see if you have any travel insurance as a benefit – most UAE banks, such as Emirates NBD, First Abu Dhabi Bank and Abu Dhabi Islamic Bank, have cards that throw in insurance as part of their package. But read the fine print – they may only cover emergencies while you’re travelling, not cancellation before a trip.
Pre-existing medical conditions such as a heart condition, diabetes, epilepsy and even asthma may not be included as standard. Again, check the terms, exclusions and limitations of any insurance carefully.
If you want trip cancellation or curtailment, baggage loss or delay covered, you may need a higher-grade plan, says Ambareen Musa of Souqalmal.com. Decide how much coverage you need for emergency medical expenses or personal liability. Premium insurance packages give up to $1 million (Dh3.7m) in each category, Ms Musa adds.
Don’t wait for days to call your insurer if you need to make a claim. You may be required to notify them within 72 hours. Gather together all receipts, emails and reports to prove that you paid for something, that you didn’t use it and that you did not get reimbursed.
Finally, consider optional extras you may need, says Sarah Pickford of Travel Counsellors, such as a winter sports holiday. Also ensure all individuals can travel independently on that cover, she adds. And remember: “Cheap isn’t necessarily best.”
